Buffer Buffer Zone
Create a buffer zone of a specified distance around any GeoJSON geometry using Turf.js.
About this tool
The PixelForge Buffer Tool creates buffer zones around GeoJSON point, line, or polygon features using Turf.js — entirely in your browser. Buffering is a fundamental GIS operation used in proximity analysis: finding all locations within a certain distance of a road, river, building, or boundary. Paste your GeoJSON, set a buffer distance in metres or kilometres, and download the buffered output as a new GeoJSON file ready for use in QGIS, ArcGIS, Mapbox, or any GIS platform.
Frequently Asked Questions
Point, LineString, Polygon, MultiPoint, MultiLineString, MultiPolygon, and FeatureCollection are all supported. The buffer is applied to each feature individually.
You can specify the buffer in metres or kilometres. Select your preferred unit from the dropdown before entering the distance.
Yes. Turf.js uses geodesic calculations that account for Earth's curvature, giving accurate results for both small and large buffer distances.
The buffer tool creates the buffer polygon. You can then use the GeoJSON Validator or a spatial query tool to check which points fall within it.
No. All buffering is done client-side using Turf.js running in your browser. Your data never leaves your device.
